PREVENTION OF DEFICIENCIES IN THE TRANSFU SIONAL PROCESS

The methods of system reliability analysis represent an interesting se t of tools used to follow the so-called <<transfusion process>>, defin ed as all the steps from donors sensitization to recipients follow-up. FMECA, (Failure Mode Effects and Criticality Analysis), can be used a s a prevention tool, independantly of any dysfunction in the process. Of course, it can equally be used following a failure, in order to ana lyse the causes and to apply the specific corrections. Quality insuran ce, system reliability analysis, epidemiologic surveillance and safety monitoring operate in synergy. These three issues pertaining to trans fusion safety constitute a dynamic system.
